DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Inovio achieves strong T cell immune responses in PENNVAX-B Phase I HIV study

Inovio Pharmaceuticals, Inc. announced today that it has achieved strong T cell immune responses in a Phase I clinical study of PENNVAX-B, its product for the treatment of the HIV subtype prevalent in North America and Europe, in HIV-positive subjects.

EBV can infect and may also contribute to lymphomas in man's best friend

More than 90 percent of humans have antibodies to the Epstein Barr virus. Best known for causing mononucleosis, or "the kissing disease," the virus has also been implicated in more serious conditions, including Hodgkin's, non-Hodgkin's and Burkitt's lymphomas. Yet little is known about exactly how EBV triggers these diseases.

Researchers discover over 500 genes that may contribute to pancreatic cancer

A global team led by scientists from The Methodist Hospital Research Institute has identified more than 500 genes that may cause or contribute to the development of pancreatic cancer.

JAK-STAT inhibitors reverse MS-like disease in mice

A new class of drugs completing clinical trials soon for rheumatoid arthritis should be examined as a treatment for multiple sclerosis, according to the authors of a University of Alabama at Birmingham study published today in the Proceedings of the National Academy of Sciences.

Researchers elucidate function of Codanin-1 protein

Within all our cells lies two meters of DNA, highly ordered in a structure of less than 10 micro meters in diameter. Special proteins called histones act as small building bricks, organising our DNA in this structure. Preservation of the structure is necessary to maintain correct function of our genes, making histones detrimental for maintaining a healthy and functional body.

UnitedHealth report: Spending on genetic tests to rise sharply in a decade

Genetic tests could become a $25 billion market by 2021. Currently, spending on these tests is estimated at $5 billion annually.

Researchers unlock mystery of how an inflammatory molecule is produced in the body

Cedars-Sinai researchers have unlocked the mystery of how an inflammatory molecule is produced in the body, a discovery they say could lead to advances in the treatment of rheumatoid arthritis, Type 2 diabetes and numerous other chronic diseases that affect tens of millions of people.

Salk scientists' discovery explains how a class of chemotherapy drugs works

The well-being of living cells requires specialized squads of proteins that maintain order. Degraders chew up worn-out proteins, recyclers wrap up damaged organelles, and-most importantly-DNA repair crews restitch anything that resembles a broken chromosome. If repair is impossible, the crew foreman calls in executioners to annihilate a cell. As unsavory as this last bunch sounds, failure to summon them is one aspect of what makes a cancer cell a cancer cell.

Researchers determine structure of concentrative nucleoside transporter

A team of researchers at Duke University has determined the structure of a key molecule that can carry chemotherapy and anti-viral drugs into cells, which could help to create more effective drugs with fewer effects to healthy tissue.

Chlamydia has evolved more actively than previously thought

In a study released today in Nature Genetics, researchers have found that Chlamydia has evolved more actively than was previously thought. Using whole genome sequencing the researchers show that the exchange of DNA between different strains of Chlamydia to form new strains is much more common than expected.

Tranylcypromine shows promise against AML

A retinoid called all-trans retinoic acid (ATRA), which is a vitamin A-derivative, is already used successfully to treat a rare sub-type of acute myeloid leukemia (AML), however this drug has not been effective for the more common types of AMLs.

Gene that causes aggression in men under stress discovered

Scientists have found that “macho” gene that makes men behave more aggressively than women under stress. They say this one gene could explain why men have a 'fight or flight' response while women are more likely to try and defuse the situation. The study has been published in the journal BioEssays.

Tumors can be more complex than imagined earlier: Study

Researchers speculate that cancers may be more complex that they knew. And that's why a single tissue sample taken from a single tumor may not be the best way to figure out a course of treatment they claim.

Five new genetic mutations linked with Crohn's disease in Ashkenazi Jews

In the largest study of its kind, researchers from Mount Sinai School of Medicine have discovered five new genetic mutations associated with Crohn's disease in Jews of Eastern European descent, also known as Ashkenazi Jews.

Researchers reveal how melanoma develops resistance to Zelboraf

Cancer is tough to kill and has many ways of evading the drugs used by oncologists to try and eliminate it. Now, researchers at UCLA's Jonsson Comprehensive Cancer Center have uncovered how an advanced form of melanoma gets around an inhibitor, Zelboraf, which targets the mutated BRAF gene.
